Direct heating of EO(Add EO into the wax t make candle) is not recommanded.
This is dangerous and possibly harmful.
You may chose another way,
using a 香薰爐(有得裝水的,drop DD EO into water and light up a candle under the reservior)
then use your hand-made candle to heat it up <-------[this is what i want!But i can't find 燈芯- -"]
